Here are 690 questions about the history of Pasadena derived from the headlines of Pasadena newspapers, as displayed in the Pasadena Pubic Library's Pasadena News Index (PNI). It started when the then head of Children's Department of the Pasadena Public Library asked the author, the local history librarian at the Library for over 20 years, to put something together for children coming to the library needing some information on the history of Pasadena. Because he felt very strongly that history is a process to be explored, rather than facts to be regurgitated, he conceptualized the work as a series of questions that would both teach some interesting facts about Pasadena, as well as give the students the skills to further explore topics that interest them on their own. Thus attached to each question is a search strategy to get a more complete answer online through the PNI and then at the library. Drawing upon the extensive newspaper archives of the Pasadena Public Library, the PNI is a comprehensive online resource of Pasadena newspaper headlines and subject headings. It provides a unique window into the history of Pasadena as seen by contemporary citizens of Pasadena. Go through all 690 questions and you will be proficient at online searching AND knowledgeable about the history of Pasadena. While the book was initially intended as an aid to teachers and home school parents to find innovative ways to teach Pasadena history, many of the facts and incidents will appeal to readers of all ages. Because each question has a larger story behind it: an 11-year-old boy who helped uncover an Indian burial ground in Pasadena; a Pasadena African-American who passed as white and served as an officer in World War One; a Pasadena woman who won a world chess championship. And 697 other stories waiting to be explored. Enjoy.
